Assessing the Believability of Standardized Patients Trained to Portray Communication Disorders

Purpose

The purpose of this study was to evaluate the believability of standardized patients portraying individuals with communication disorders as part of a larger study in which standardized patients help train medical and allied health students about communication disorders.

Method

Two women portrayed persons with aphasia, and 2 men depicted persons with dysarthria associated with Parkinson's disease. Two stakeholder groups rated believability. Speech-language pathologists rated believability of videos online. Persons with aphasia rated aphasia videos during in-person sessions with the researchers.

Results

Targeted believability was 80 or higher (0–100 scale; 0 = not at all believable, 100 = very believable). For speech-language pathologist raters, average ratings met the target for the portrayals of the aphasia characteristics of word-finding problems, agrammaticism, nonverbal communication, and overall portrayal but not for auditory comprehension problems. Targets for the portrayals were met for the dysarthria characteristics of reduced speech movements, reduced loudness, reduced intonation, flat affect, and overall portrayal but not for speech rate. Ratings for different standardized patients portraying the same case were not significantly different from each other on most characteristics. Ratings from persons with aphasia were highly variable.

Conclusion

Standardized patients who do not have communication disorders can portray disorder characteristics in a believable manner.
